The use of GIS applications in the elections

The conditions for the use of GIS software in re-partitioning can be divided into the following three categories: computer systems and software, spatial data and other data, and users. In addition, the general understanding of GIS and the potential advantages and disadvantages of using it, as well as the frame of reference that allows for its use, are all important considerations when GIS is adopted to demarcate constituencies. Computer systems and software GIS software works on all types of computer systems ranging from PCs to multi-user computers. Regardless of the hardware components selected, there are a number of elements that must be considered in order for GIS software to function effectively: The computer must be equipped with a processor of sufficient capacity (in terms of speed and RAM) to operate the GIS software and sufficient disk space to store large amounts of data And a high-resolution color graphics display screen; Data entry devices such as digital adapters and scanners If paper data must be converted into electronic data Data output devices such as printers and plotters. Conditions of hardware components depend on and determine software requirements; limitations of hardware components may mean that certain software products can not be used, while the availability of software can dictate the type of hardware to be purchased. Software refers to both the operating system and specific application packages. GIS applications work with a variety of operating systems such as Unix, Windows NT and Windows XP using geographic information systems such as Arc / Info, Intergraph, MapInfo, Maptitude, or GIS software packages for redistricting. Cost can be a key factor in hardware and software selection. Budgetary constraints, especially in many developing countries, limit the freedom to choose which computer system and software can be used. Data The data includes both the cartographic database needed for the use of GIS applications, as well as any associated metadata (primarily demographics related to redistribution). The availability and accuracy of data, in particular the availability of digital map data, are among the most important prerequisites for the development of GIS capabilities. The amount of use of GIS is often determined by the availability of digital map data, or, most often, the willingness to devote the resources needed to create such a database. Many countries have produced a full set of unified digital maps covering the entire country, but others have just started, or are not yet, in the process. Developing countries face a number of constraints on the use of GIS applications that revolve around issues such as cost, training of specialized personnel and availability of data. With the need to resolve issues related to the exploitation of urban and rural land, transport, housing and environmental pollution, pressure has begun to adopt GIS technology and develop computerized maps that can then be adapted for re-demarcation. Users Users are referred to trained personnel who are able to operate the GIS. The main requirement for GIS users is the ability to work with computers to deal with basic software and GIS databases as well as some geographic and cartographic information in order to be able to use GIS to demarcate constituencies.
